Current IssueThe Hole Truth: Via Integrity in an HDI World
From the drilled hole to registration across multiple sequential lamination cycles, to the quality of your copper plating, via reliability in an HDI world is becoming an ever-greater challenge. This month we look at “The Hole Truth,” from creating the “perfect” via to how you can assure via quality and reliability, the first time, every time.
In Pursuit of Perfection: Defect Reduction
For bare PCB board fabrication, defect reduction is a critical aspect of a company's bottom line profitability. In this issue, we examine how imaging, etching, and plating processes can provide information and insight into reducing defects and increasing yields.
Voices of the Industry
We take the pulse of the PCB industry by sharing insights from leading fabricators and suppliers in this month's issue. We've gathered their thoughts on the new U.S. administration, spending, the war in Ukraine, and their most pressing needs. It’s an eye-opening and enlightening look behind the curtain.

Focus Tech Announces New Website and Product Showcase
March 28, 2023 | Focus TechEstimated reading time: 1 minute

Tempe, Arizona based Focus Tech announces a new website that focuses on its offering in specialty chemical and process control system manufacturing for the printed circuit board and general metal finishing industries. Focus Tech is the only supplier to the PCB industry that designs and manufactures both process chemicals and control systems.
“Focus Tech is proud to roll-out a new company website this week,” commented Scott Campbell, Focus Tech founder and president. “The site www.focustechchem.com features over 50 product pages for a variety of chemicals we manufacture for a variety of applications. In two clicks, viewers will find technical information on what we offer. We designed it from the ground up to make it easy to access and navigate all our information.”
Focus Tech product lines include anti-foam, anti-tarnish, copper cleaners, etch chemicals, developers, strippers, as well as others commonly used in the manufacture of printed circuit boards and general metal finishing. Focus Tech also manufactures process control equipment and offers a variety of services to PCB fabricators.
Focus Tech is known for responding quickly to customer needs and evolving technology by providing custom chemical formulations and controller designs tailored to the specific requirements of a given process.
Campbell added, “Last year, we moved to a new 47,000 square-foot facility with significant capital investment to improve and streamline all operational, research & development, and manufacturing processes. This has allowed Focus Tech to expand its capabilities particularly in toll blending capabilities. One click on the website will take viewers to a robust overview of what we can do in chemical blendings, custom process controls, and services.
“Our new R&D laboratory allows various types of testing including wet titration, atomic absorption and UV/VIS spectroscopy, and cross sections. Our access to a scanning electron microscope and energy dispersive x-ray analysis equipment round out our test services.”
A part of The Redfern Companies, Focus Tech’s products, equipment, and services are distributed by Insulectro leveraging the distributor’s sales team and 11 stocking locations in North America.

Digital Twin Concept in Copper Electroplating Process Performance
07/11/2025 | Aga Franczak, Robrecht Belis, Elsyca N.V.PCB manufacturing involves transforming a design into a physical board while meeting specific requirements. Understanding these design specifications is crucial, as they directly impact the PCB's fabrication process, performance, and yield rate. One key design specification is copper thieving—the addition of “dummy” pads across the surface that are plated along with the features designed on the outer layers. The purpose of the process is to provide a uniform distribution of copper across the outer layers to make the plating current density and plating in the holes more uniform.
Trump Copper Tariffs Spark Concern
07/10/2025 | I-Connect007 Editorial TeamPresident Donald Trump stated on July 8 that he plans to impose a 50% tariff on copper imports, sparking concern in a global industry whose output is critical to electric vehicles, military hardware, semiconductors, and a wide range of consumer goods. According to Yahoo Finance, copper futures climbed over 2% following tariff confirmation.
Happy’s Tech Talk #40: Factors in PTH Reliability—Hole Voids
07/09/2025 | Happy Holden -- Column: Happy’s Tech TalkWhen we consider via reliability, the major contributing factors are typically processing deviations. These can be subtle and not always visible. One particularly insightful column was by Mike Carano, “Causes of Plating Voids, Pre-electroless Copper,” where he outlined some of the possible causes of hole defects for both plated through-hole (PTH) and blind vias.
